A Whiff of History: The Rise of Scratch-and-Sniff

Before they showed up in sticker books and classrooms, scratch-and-sniff stickers began in a lab, not too different from Dr. Stinky’s own!
The invention that made it all possible was microencapsulation, a process first developed in the early 1960s by scientists at the National Cash Register Company. They discovered how to trap tiny liquid droplets inside microscopic capsules that would burst under pressure (when they were scratched, for example).

Originally, those tiny capsules held ink, but the breakthrough led researchers to another idea: what if those capsules held scents instead? Suddenly, printed scents were everywhere.

By the 1970s, the technology was used to print scented inks in advertising (remember sniffing a new perfume in a magazine?), children’s books, and before long, stickers. By the 1980s, scratch and sniff stickers were everywhere: on notebooks, in classrooms, and traded by kids who couldn’t resist another sniff.

Today, people of all ages are scratch-n-sniff fans, and they’re passionate about sticky stinks! Dr. Stinky’s is proud to make the world’s stinkiest stickers using the same microencapsulation technology. It’s the only choice for discerning sniffers!

Why We Still Love Scratch-and-Sniff Stickers

The best smells aren’t just smells — they’re memories. Think about it:

🍿A whiff of popcorn might take you back to your favorite film
🥤A hint of lemonade brings up sunny summer afternoons
🐶Even a stinky scent like Wet Dog has the power to remind us of life’s silly moments

Scratching a sticker and leaning in to take a whiff can be a powerful memory all on its own. It’s an experience you can share across generations, any time, and for any reason. These smelly stickers connect scent and memory in a way that feels both personal and playful. They’re tiny time machines; one scratch, and suddenly you’re ten years old again.
